Ab Crunch Machine

The machine crunch is a machine-based exercise targeting the abdominal muscles. It involves sitting upright in the machine and curling the torso down toward the chest against some pre-set level of resistance. On some machines, the knees also curl up torward the torso. Crunch machines usually use extra resistance in the form of selectorized weight stacks or plate loading, and are often performed for moderate to high reps, like 8-12 reps per set or higher, as part of the ab-focused portion of a workout.
